PURPOSE: Although laparoscopic adjustable gastric banding (LAGB) is a popular bariatric procedure, few comprehensive studies have been investigated on the use of non-gastro-gastric sutures (NGGSs) for decreasing postoperative complications. This study aimed to assess and compare the safety and effectiveness of MIDBAND with or without gastro-gastric sutures (GGSs). METHODS: Between February 2013 and March 2014, 41 severely obese patients underwent primary LAGB using pars flaccid technique at double center in South Korea. Excess weight loss, operative time and postoperative complications were assessed and compared between a GGS group (group 1) and a NGGS group (group 2), and patients were followed monthly for 1 year. RESULTS: Mean body mass indices in groups 1 and 2 were 38.4 ± 4.7 and 38.9 ± 5.0 kg/m², respectively, and mean percentage excess weight losses (%EWLs) were 59.9% ± 28.4% and 50.9% ± 20.0%, respectively, at 6 months, and 75.8% ± 26.6% and 72.5% ± 27.5%, respectively, at 12 months, and these intergroup differences of %EWL were not significant (P = 0.256 and P = 0.704, respectively). Mean operative time (57.2 minutes) was shorter in group 2 than in group 1 (79.2 minutes) (P < 0.001). In terms of complications, pouch dilatation rates were similar in the 2 groups, and no case of gastric band erosion was encountered. CONCLUSION: Operative time was shorter in the NGGS group, and pouch dilatation rates and %EWL were similar in the 2 groups. We conclude NGGS using MIDBAND is both straightforward and effective. A long-term prospective comparative study is needed to demonstrate the safety and efficacy of NGGS.

Obesity and metabolic syndrome affect ~40% of individuals in the United States alone. They are significant conditions that can cause severe economic problems. Obesity is also a global issue, with ~400 million obese adults worldwide. Moreover, the number of overweight children is increasing. Bariatric surgery is the gold standard treatment for obesity; however, endoscopic approaches may have a significant role in improving metabolic syndrome and achieving weight loss. Many endoscopic methods have been introduced, some of which are currently available and some that are undergoing experimentation. Endoscopists have a role in the treatment of obesity because endoscopic therapies are expected to become safer and more efficacious in the coming years. Endoscopic bariatric therapies can be categorized as space occupying, malabsorption, and gastric volume reduction. In this review, we summarize the currently available endoscopic procedures.

Bariatric surgery is considered to be the most effective treatment modality in maintaining long-term weight reduction and improving obesity-related conditions in patients that are morbidly obese. Since 2003 when the first bariatric surgery was performed in Korea, the annual number of cases has markedly increased. The adjustable gastric banding procedure is known to be less invasive and less destructive than gastric bypass or sleeve gastrectomy, and it is unique that the proportion of this procedure is much higher in Korea than in other countries. This phenomenon arises from a misunderstanding that bariatric surgery has an unacceptably high morbidity rate and that it is not superior to nonsurgical treatment to improve obesity and related diseases. To overcome this misunderstanding, it is essential for doctors as well as patients to understand that obesity is a disease entity that requires an intensive treatment and to comprehend that bariatric surgery is a viable treatment for obesity.

The emerging endoscopic technologies are proved to be effective treatments for obesity in selected patients and to offer the potential advantages of reduced invasiveness, reversibility and repeatability. From the view of operation principle, endoscopic technologies can be classified as restrictive procedure, malabsorption procedure and endoscopic revision of gastric bypass. Restrictive procedures include intragastric balloon, aspiration therapy, endoscopic sleeve gastroplasty (ESG) and transoral gastroplasty. Intragastric balloon employs space occupying, volume restriction and satiety mechanisms, which is superior to drugs and lifestyle change, but shorter than sleeve and bypass surgery. Aspiration therapy is similar to standard percutaneous endoscopic gastrostomy, while there are no available data regarding the obesity and metabolic improvement. Compared with traditional bariatric surgery, ESG does not excise gastric tissue with less complications and without weight regain, but it can not be used as an independent operation still now. Transoral gastroplasty is rarely applied clinically whose efficacy and long-term complications need further studies. Malabsorption surgery includes endoscopic duodenojejunal bypass sleeve (EDJBS) and endoscopic gastroduodenojejunal bypass sleeve(EGDJBS). EDJBS may have the similar mechanism like bypass reducing the blood glucose. Even with obvious effect of weight loss, EDJBS has high morbidity of complications and requirements of the skilled operators. EGDJBS, which imitates bypass anatomy changes and belongs to the mixed operation, should be superior to the above procedures in reducing weight theoretically, but due to the lack of clinical data, its short-term and long-term efficacy still need further clinical observation. As compared to the complexity and risks associated with telescopic surgical revision, endoscopic suturing has been confirmed as less invasive and safer for stomal revisions, while its long-term efficacy of reducing weight and improvement of diabetes are not yet clear. Even if long-term efficacy of reducing weight and morbidity of complication in endoscopic bariatric surgery are still indefinite, and clinical trial researches of large sample and long-term follow-up are absent, with the development of endoscopic skill and the gradual clinical application, endoscopic bariatric surgery will provide a new option for the patients of obesity and metabolic diseases.

Bariatric-metabolic surgery (BMS) has the potential of decreasing body weight and improving obesity-related metabolic syndrome by restricting food intake and malabsorption. Laparoscopic sleeve gastrectomy, Roux-en-Y gastric bypass, adjustable gastric banding, biliopancreatic diversion with duodenal switch are four major BMS procedures. Sleeve plus surgery, one-anastomosis gastric bypass, intragastric balloon and endoscopic surgery are also arising and gaining popularity due to their specific efficacy. Currently, BMS is now experiencing an era with deeply integrated interdisciplinarity, optimizing and innovating of surgeries and well-illustrated clinical efficacy, as a result, more obese patients would benefit from BMS.

Along with the soaring prevalence of obesity and type 2 diabetes mellitus (T2DM) globally, metabolic and bariatric surgery (MBS) has been rapidly developing into a major surgical subspecialty. However, the indications, benefits and potential risks of MBS are still controversial so far. In September 2015, the 2nd Diabetes Surgery Summit (DSS-II() was successfully convened, and later on an international joint statement on metabolic surgery in the treatment algorithm for T2DM was released based upon the consensus reached in DSS-II(, aiming to serve as a new global clinical guideline. The DSS-II( joint statement was initiated and endorsed by 5 leading international diabetes organizations, including American Diabetes Association (ADA), International Diabetes Federation (IDF), Chinese Diabetes Society (CDS), Diabetes India, as well as Diabetes UK, and was developed by an expert committee comprised of 48 international authorities as voting delegates. Up to the date of publication, the DSS-II( statement has been officially endorsed by 45 international professional associations/societies, including 30 non-surgical and 15 surgical organizations. In this statement, the following six aspects were recommended to differentiate MBS from traditional bariatric surgery: 1)The primary goal of MBS is to treat T2DM and to reduce the risk of T2DM complications; 2) In addition to a 50% or more of excess weight loss and normalization of glycemia, outcomes of diabetes complications should also be considered as clinical endpoints of MBS; 3) For patient selection, body mass index (BMI), T2DM treatment, as well as long-term risks versus benefits, including its effects on cardiovascular events (CVD), should all be considered; 4) T2DM and its complications, as well as pancreatic function reserve should be assessed pre-operatively; 5) Major surgical options include laparoscopic Roux-en-Y gastric bypass (LRYGB), laparoscopic sleeve gastrectomy (LSG), laparoscopic adjustable gastric banding (LAGB), and bilio-pancreatic diversion with duodenal switch(BPD-DS). BPD-DS has the best outcome in T2DM remission followed by LRYGB, LSG and LAGB; 6) Glycemic variation should be intensively monitored, and if needed, managed following surgery. Clinical follow-up should be conducted at least once every six months within two years after surgery. For patients achieving complete remission from T2DM, diabetes complications should still be monitored within five years after surgery with the same frequency and protocols as pre-operatively.

Health and wellness represent a major global concern. Trends such as a lack of exercise and excessive consumption of calories are major causes of the rapid increase in obesity worldwide. Obesity should be controlled because it can result in other illnesses, such as diabetes, high blood pressure, high cholesterol, coronary artery disease, stroke, breathing disorders, or cancer. However, many people have difficulty in managing obesity through exercise, dietary control, behavioral modifications, and drug therapy. Bariatric surgery is not commonly used due to a variety of complications, even though it has been demonstrated to produce reliable results with respect to adequate weight loss when performed using an open or a laparoscopic approach. Endoscopic bariatric procedures are emerging techniques that are less invasive and safer compared with current surgical approaches. However, the evaluation of endoluminal procedures is limited by the small number of studies and their short-term follow-up.

Obesity and its associated metabolic diseases including diabetes mellitus are severe medical problems that are increasing in prevalence worldwide and result in significant healthcare expenses. While behavioral and pharmacological treatment approaches are partly effective in the short term, their effects are not long-lasting. Although previous studies have described bariatric surgery as the most effective treatment for obesity, it is associated with morbidity, mortality, and economic burden. Endoluminal interventions performed entirely using gastrointestinal flexible endoscopy offer alternative approaches to the treatment of obesity that are safer and more cost-effective than current surgical approaches. The use of endoluminal techniques in the field of metabolic obesity disease has diverse promising applications including endoscopic gastroplasty, intragastric balloon, endoluminal malabsorptive bariatric procedures, and gastric electrical stimulation (GES) for the modulation of gastric emptying. This review discusses recent trends and roles in endoscopic bariatric therapies using the currently available endoluminal and transgastric technologies.
